Data Sheet
Dual LDO with Low Noise, Low IQ, and
High PSRR
ISL9011 is a high performance dual LDO capable of
sourcing 150mA current from channel 1 and 300mA from
channel 2. The device has a low standby current and high-
PSRR and is stable with output capacitance of 1µF to 10µF
with ESR of up to 200m.
A reference bypass pin allows an external capacitor for
adjusting a noise filter for low noise and high PSRR
applications.
The quiescent current is typically only 45µA with both LDO’s
enabled and active. Separate enable pins control each
individual LDO output. When both enable pins are low, the
device is in shutdown, typically drawing less than 0.1µA.
Several combinations of voltage outputs are standard.
Others are available on request. Output voltage options for
each LDO range from 1.2V to 3.6V.
